About Cups
A cup = 8 fl oz = 16 tbsp ≈ 236.6 mL - the fundamental unit of American cooking. Almost every US recipe uses cups for dry and liquid ingredients. The US customary cup (236.588 mL) differs from the US legal cup (240 mL, used in nutrition labelling) and the metric cup (Australia/Canada: 250 mL). Kitchen sets come in 1/4, 1/3, 1/2, and 1 cup sizes. 2 cups = 1 US pint.
About Gallons
A US gallon (gal) = 4 quarts = 128 fl oz ≈ 3.785 L. Gasoline, milk, water, paint, and pesticides are sold by the gallon in the US. About 20% smaller than the UK imperial gallon (4.546 L) - a critical difference when comparing fuel economy across the Atlantic. 1 US gal = 3.785 L = 4 qt = 128 fl oz.
